Crystal Caves 1: Troubles with Twibbles is a side-scrolling action platformer released by Apogee Software for DOS in 1991. Players control the space-faring prospector Mylo Steamwitz, navigating hazardous underground mines across a series of planets to collect valuable crystals and fund a business venture.
How to play
To complete each level, you must gather every crystal to open the exit doors while surviving hostile alien life and environmental hazards. You can use the arrow keys to move, the Alt key to jump, and the Ctrl key to fire your rocket launcher. If playing in the browser, press Right Alt + Enter to toggle full-screen mode.
Tips
- Your rocket ammo is limited, so try to avoid enemies when possible rather than shooting everything you see.
- Gravity in the caves can be tricky; hold the jump key to jump higher, and time your leaps carefully over hazards like spikes and slime.
- Some blocks can be shot or stood upon to reveal hidden items, so explore carefully if you are missing a crystal.
